[PATCH 3/5] drm/i915/display: Enable the second scaler for sharpness
Nemesa Garg
nemesa.garg at intel.com
Fri Jul 5 09:02:03 UTC 2024
As only second scaler can be used for sharpness check if it
is available and if panel fitting is also not enabled, the
set the sharpness. Panel fitting will have the preference
over sharpness property.
v2: Added the panel fitting check before enabling sharpness
